How do I add an automatic value to something with saving and loading?

I want to make something have an automatic value when you join the game, and you can change the value in shops. But when I join, it sets the value, and then loads in 0 because it saved 0 from when I leave the game. Is there a way to fix this?

Script:

local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("myDataStore")

-----------------Loading Data------------------
game.Players.PlayerAdded:Connect(function(player)
	
	--Upgrades
	
	local Upgrades = Instance.new("Folder")
	Upgrades.Name = "Upgrades"
	Upgrades.Parent = player
	
	
	
	
	local Multiplier = Instance.new("IntValue")
	Multiplier.Name = "Multiplier"
	Multiplier.Value = 1
	Multiplier.Parent = Upgrades
	local MultPrice = Instance.new("IntValue")
	MultPrice.Name = "MultiplierPrice"
	MultPrice.Value = 10
	MultPrice.Parent = Multiplier
	
	
	local Backpack = Instance.new("IntValue")
	Backpack.Name = "Backpack"
	Backpack.Value = 5
	Backpack.Parent = Upgrades
	local BpPrice = Instance.new("IntValue")
	BpPrice.Name = "BackpackPrice"
	BpPrice.Value = 10
	BpPrice.Parent = Backpack
	
	
	
	local playerUserId = player.UserId
	
	
	--Load Data
	local data
	local success, errormessage = pcall(function()
		data = myDataStore:GetAsync(playerUserId)
	end)

	if success then
		if data then
			for i, v in pairs(Upgrades:GetChildren() and Upgrades:GetDescendants()) do
				for dataValue, _ in pairs(data) do
					if dataValue == v.Name then
						v.Value = dataValue
					end
				end
				
			end
			
			
		end
		-- Set our data equal to the current Cash
	end

	--pcalls protect you from getting errors.
end)



-----------------------Saving Data-------------------------
game.Players.PlayerRemoving:Connect(function(player)
	local playerUserId = player.UserId
	
	
	local data = {}
	
	for i, v in ipairs(player.Upgrades:GetChildren() and player.Upgrades:GetDescendants()) do
		data[v.Name] = v.Value
	end

	
	
	local success, errormessage = pcall(function()
		myDataStore:UpdateAsync(playerUserId, function(oldData)
			local previousData = oldData or {DataId = 0}
			if data.DataId == previousData.DataId then
				return data
			else
				return nil
			end
		end)
	end)
	
	
	
end)

Since datastores can take a while to load player data you should create a bindable event that fires only after the data is loaded

local player_data_loaded = game.ServerStorage.PlayerDataLoadedEvent

game.Players.PlayerAdded:Connect(function(player)
    -- etc ...
    local data
	local success, errormessage = pcall(function()
		data = myDataStore:GetAsync(playerUserId)
	end)

	if success then
     		player_data_loaded:Fire(player)
	-- etc ...

Then instead of giving a value on player added, use the event

local player_data_loaded = game.ServerStorage.PlayerDataLoadedEvent
player_data_loaded.Event:Connect(function(plr)
	plr.leaderstats.AutoValue.Value += 1
end)
